Current study is focusing mainly on the development of simple, novel, and cost-effective optical sensor to detect and quantify Bisphenol A (BPA) contamination. We designed a very selective and sensitive colorimetric sensor using synthesized 3', 6'- bis(diethylamino) -2- ((3,4,5 trimethyl benzylidene) amino)spiro [isoindoline-1,9'-xanthen] -3-one (BTSIXO) conjugated with Fe-ions via very simple eco- friendly synthetic protocol. The sensor has an excellent wide detection range for BPA from 0.1 to 150 ppm with LODs of 0.02 ppm. Finally, the applicability of the sensor was demonstrated in fish samples especially in the organs of Oreochromis mossambicus fingerlings and contaminated industrial water samples. The sensor was also applied for the quantification of BPA present drinking water stored in the plastic bottles. The developed sensor has shown a good agreement and accuracy when compared with ESI-Mass techniques.
目前的研究主要集中在开发简单、新颖且具有成本效益的光学传感器，以检测和量化双酚 A (BPA) 的污染。我们设计了一种非常选择性和灵敏的比色传感器，使用合成的 3'，6'-双(二乙氨基)-2-((3,4,5-三甲苄叉基)氨基)螺[异吲哚啉-1,9'-氧杂蒽]-3-酮 (BTSIXO) 通过非常简单的环保合成方案与 Fe 离子偶联。该传感器对 BPA 具有极好的宽检测范围，从 0.1 到 150 ppm，LOD 为 0.02 ppm。最后，该传感器在鱼类样本中的适用性得到了证明，特别是在奥利亚罗非鱼幼鱼的器官和受污染的工业水样中。该传感器还用于定量测定储存在塑料瓶中的饮用水中的 BPA。与 ESI-Mass 技术相比，所开发的传感器显示出良好的一致性和准确性。
